At 21.50 hours on 5 May 1943, U-266 fired four torpedoes at convoy ONS-5 and reported one ship sunk, one probably sunk and that two detonations had been heard. In fact the three ships Selvistan, Gharinda and Bonde on stations #91, #101 and #84 were hit within three minutes and all sank.
The Bonde (Master Finn Abrahamsen) was the smallest ship in convoy and was hit by one torpedo and sank slowly. Eleven survivors were picked up from a lifeboat and a raft by the British frigate HMS Tay one hour later. The master was allowed to go back to his ship and found another survivor.
